The high quality PYREX® borosilicate glassware coupled with silica sheathed heaters gives pyrogen free distillate of the highest purity from virtually any raw water supply.

The unique condenser design ensures that the droplets of distilled water remain in contact with the cooling coil for the longest possible time ensuring maximum energy transfer. This produces cold distilled water ready for immediate use and pre-heats the boiler feed to increase efficiency. All glass construction allows rapid descaling using strong mineral acids. A built in " clean" function and integral acid addition funnel make the cleaning operation simple and safe with no need to dismantle any of the glassware. A large bore ROTAFLO ® stopcock with PTFE key is fitted for easy draining of chemicals after cleaning.

A flow sensing device will detect any reduction in the flow of cooling water to below the required level and will turn off the still before it can overheat. Sensing the flow of cooling water rather than its pressure is safer and allows the still to run normally on low pressure supplies down to 3psi ( 20kPa) . As a fail-safe device there is an over-temperature thermostat mounted in the boiling chamber.

The Aquatron is very easy and safe to assemble and maintain. Both the acrylic safety screen and the cabinet lid are removable giving unrivalled access to the glassware components. Screwthreads are incorporated on all water connections so hoses can be fitted and removed easily and safely without risk of breakage. Every Aquatron® water still is supplied with a reservoir level control.

The control is a simple and effective system which can be fitted to virtually any type of reservoir vessel. It will turn the still off when the reservoir is full and restart it when the level in the reservoir drops as distilled water is removed for use making it fully automatic.

Aquatron® models: -

A4000 Produces 4 litres/ hour single distilled water. Can operate standing on the laboratory bench or be wall mounted. Supplied with easy to fit wall mounting bracket.

A8000 Produces 8 litres/ hour single distilled water, ideal for the larger laboratory. Glassware is enclosed in the same cabinet as the A4000 so can operate standing on the laboratory bench or be wall mounted. Supplied with easy to fit wall mounting bracket.

A4000D Produces 4 litres/ hour double distilled water for higher purity levels. The first stage distillation is carried out in a glassware set mounted at the front of the cabinet allowing easy access for descaling. The distilled water is fed to a second set of glassware mounted at the rear and distilled a second time. The rear glassware is fitted with a level sensor to ensure the heater is only activated when there is sufficient water in the boiler.

Conversion to pre-treated feed: -

Simple conversion kit is available so that the Aquatron® water still can be operated from a pre-treated feed. Suitable sources of pretreatment are almost any model of deioniser or reverse osmosis unit or a piped supply of treated water.

The pre-treated water is fed directly to the boiler and cooling water is supplied to the condenser separately. The controls ensure that pre-treated water is supplied to the boiler automatically as required, preventing overflow and costly waste. A safety device is incorporated to protect the still in the event of failure of the pretreated supply.
The conversion kit can be fitted easily in a few minutes to any existing Aquatron® model should the need arise.

The Aquatron® deioniser is the perfect partner for the Aquatron® water still.

* pH, conductivity and resistivity are affected by temperature and the presence of absorbed carbon dioxide. The basis of the tests is 20° C on distilled water free of carbon dioxide.

* * Care is needed to obtain Pyrogen-free water and the distillate must be tested before use
